Introduction
Introduction
Vehicle Identification Numbers (VIN)
VIN ranges are presented throughout the book in the following manner:
-> VIN 123456 indicates "up to VIN 123456"; VIN 123456 -> indicates "from VIN 123456 on".
Jaguar XK Range Electrical System Architecture
The vehicle electrical system is a ground side switched system. The ignition switch switches ground circuits on / off to complete system circuits and
apply power. Circuits that require ignition switch position control are supplied with "ignition switched grounds". Both power grounds (high current
consumers) and logic grounds (electronic switching circuits) are used throughout the system.
Three data networks are employed in the vehicle: a high speed Controller Area Network (CAN) for the engine, drive train and related systems, a
Standard Corporate Protocol network (SCP) for the body systems, and an Audio Control Protocol network (ACP) for certain In-Car Entertainment and
Telephone functions. Any vehicle subsystem depicted on the figures with the CAN or SCP included uses data derived from the network, or transmits data
via the network to achieve control. Messages for both networks are cataloged in the Appendix of this book. In addition to the two networks, the vehicle
uses a serial data bus (ISO) for diagnostics, security sounder operation and for the programming of certain control modules.
